Tailoring the slow light behavior in terahertz metasurfaces
(AIP Publishing, 2015-05-04)
We experimentally study the effect of near field coupling on the transmission of light in terahertz metasurfaces. Our results show that tailoring the coupling between the resonators modulates the amplitude of resulting ...
Modulating the fundamental inductive-capacitive resonance in asymmetric double-split ring terahertz metamaterials
(AIP Publishing, 2011-03-24)
We investigate resonant transmission of planar asymmetric metamaterials made from double split-ring resonators. As the symmetry of the unit cell resonator is broken by displacing the two gaps away from the center in opposite ...
Ultrasensitive terahertz sensing with high-Q Fano resonances in metasurfaces
(AIP Publishing, 2014-10-27)
High quality factor resonances are extremely promising for designing ultra-sensitive refractive index label-free sensors, since it allows intense interaction between electromagnetic waves and the analyte material. Metamaterial ...
Probing the transition from an uncoupled to a strong near-field coupled regime between bright and dark mode resonators in metasurfaces
(AIP Publishing, 2014-08-27)
The coupling of multiple plasmonic resonators that sustain bright or dark modes provide intriguing spectral signatures. However, probing the onset of coupling effects while engaging the resonators with an increasing proximity ...
